United Airlines has begun physically covering built-in webcams on in-flight entertainment devices following privacy concerns, according to a report from BuzzFeed. The screens, enterprise-grade tablets provided to United by the aviation equipment division of Panasonic, are said to come with built-in webcams by default. United claims it never ordered webcams on its in-flight systems.

The screens, enterprise-grade tablets provided to United by the aviation equipment division of Panasonic, are said to come with built-in webcams by default, with Panasonic executives claiming the cameras could one day provide improved entertainment features like seat-to-seat video calling and even gaming. United claims it did not specially order its screens with webcams.

The privacy controversy first emerged earlier this year when some passengers, most notably cybersecurity researcher Vitaly Kamluk, began noticing webcams on seatback screens. The initial outcry was over Singapore Airlines’ inclusion of the webcam-equipped screens without informing passengers and without disclosing whether the webcams were active. However, it was soon discovered that Panasonic Avionics, a leading supplier of in-flight entertainment systems, has also been supplying US airlines like American and United with similar webcam-equipped screens. — Nick Statt/@verge
